Installing the Ethernet cable
The SmartNode 2292 Series has automatic MDX (auto-cross-over) detection and configuration on the Ether-
net ports. Any of the two ports can be connected to a host or hub/switch with a straight-through wired cable
(see
figure 10
on page 27). Ethernet devices (10Base-T or 100Base-T) are connected to the SmartNode’s
Ethernet ports (see
table 6
for port pin-out listing) via a cable terminated with RJ-45 plugs. Because the Smart-
Node 2294 Series does not have the MDX feature, a cross-over cable is required when connecting SmartNode
2294 Series devices to a host (see
figure 11
on page 28).
Note
Pins not listed are not used.
